Professional SA588 grade B carbon steel plate sheet with element chemical composition

Design of smelting composition and smelting process of SN400A, SN400B, SN400C steel, SA588 grade B carbon steel plate sheet product: The smelting process adopts low-sulfur molten iron and low-sulfur scrap on the basis of the general process flow of steel for export, adding the refining process of LIIF furnace deep desulfurization and SiCa treatment. In this way, the sulfur content in the steel can be reduced, and the sulfide in the steel can be modified. Greatly improve the toughness of steel and improve the casting performance of molten steel, and increase the qualification rate of the tundish temperature to ensure smooth casting.

Welded steel pipe refers to the steel pipe with a joint on the surface which is welded after the steel strip or steel plate is bent and deformed into circular, square and other expected shapes. According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency resistance welded pipe, gas welded pipe, furnace welded pipe, Bondi pipe, SA588 grade B carbon steel plate sheet, etc. According to the weld shape, it can be divided into straight welded pipe and spiral welded pipe. Electric welded steel pipes are mainly used in oil drilling and production, machinery manufacturing, etc.; furnace welded pipes can be used as water gas pipes, large-diameter straight seam welded pipes for high-pressure oil-gas transmission, etc.; spiral welded pipes are used for oil-gas transmission, pipe piles, piers, etc. Welded steel pipe has lower cost and higher production efficiency than seamless steel pipe.
